Fig. 4From: Genome-wide identification and characterization of transfer RNA-derived small RNAs in Plasmodium falciparumCleavage sites and motif analysis of ptRFs. a Cleavage sites of ptRFs in mature tRNA, employing the secondary structure of tRNAs-GlnCTG as an example. Brown arrowheads show the cleavage to generate 5'ptRFs, green arrowheads demonstrate the cleavage sites for mid-ptRFs, and pink arrowhead indicates the cleavage points for 3'ptRFs. b Schematic representation of the motif sequences and locations at the cleavage sites of the ptRFs. Arrowheads are the same as for panel aBack to article page
